[iOS Remote] Previously connected desktop hosts disappeared and Remote resets to “Set up Remote”

Summary

Codex Remote on iPhone suddenly lost all previously connected desktop hosts at the same time. The Remote screen now behaves as if Remote has never been configured and shows “Set up Remote” instead of the existing device list.

The affected desktops had already been connected and usable through Remote before this happened. The devices were not intentionally removed one by one.

Client

• Remote client: ChatGPT on iPhone
• ChatGPT app build observed in this session: 1.2026.230
• Same ChatGPT account is being used
• Screenshot available showing the current Set up Remote screen

What happened

1. Multiple desktop computers were previously connected and visible in Codex Remote on iPhone.
2. Remote had been working normally.
3. All connected desktop hosts suddenly disappeared from the mobile Remote device list.
4. Opening Remote now shows the first-time setup screen:
   • Set up Remote
   • “To get started, sign into the ChatGPT desktop app with your account”
   • I’m signed in on desktop
   • Email me a download link
5. There is no indication in the mobile UI that the previously paired hosts are merely offline. They are absent entirely.

Expected behavior

Previously paired/registered desktop hosts should remain associated with the account and appear in Remote, even if temporarily offline. A transient discovery or backend issue should not make the mobile client fall back to the first-time setup state or make all registered hosts appear deleted.

If the backend cannot currently discover the hosts, the app should ideally distinguish between:

• paired but offline/unreachable hosts, and
• an account with no Remote hosts configured.

Actual behavior

All previously connected hosts disappeared simultaneously and the iPhone app now presents Remote as unconfigured.

Why this may be useful diagnostically

Because multiple hosts disappeared at once, this looks more consistent with an account-side Remote registry/discovery/session-state problem or a mobile client regression than with all desktop machines independently losing their pairing at the same moment.

A related recent report is #41638, where Remote pairing is acknowledged but the mobile app still shows no connected devices. That report is Android/Linux; this report concerns an iPhone client where already-established hosts vanished simultaneously.

Additional information

Please check whether existing Remote host registrations can become temporarily invisible to iOS/mobile clients, and whether those registrations should automatically reappear when the backend/discovery state recovers.

No account email, pairing codes, host names, device IDs, tokens, or other identifying information are included in this public report.

No repository files or tests are identified. Start by tracing the iOS Remote host-list and account registration or discovery entry points, then reproduce the simultaneous disappearance of paired hosts. Done means existing hosts remain associated with the account and the UI distinguishes offline hosts from an unconfigured account.
